To all whom it may concern:

Be itknown that I. J OSEPH H. ALANDAR, a

L citizen of the United States, residing at Chicago, in thecounty ofCook and State of Illinois, have invented certain newand usefulImprovements in Railway Signal Apparatus, of which the following is aspecification. i

My inventionrelates to railway signal apparatus and its object is toprovide a means for indicating the approach tostations of a trainor caron a railway.

My inventionconsists in the partsand in the details of construction andarrangement of parts, aswill' hereinafter be more fully described andclaimed.

on the vehicle.

The installation of my improved signal apparatus in itspreferredconstruction involves the use of the contact board 1 mounted on thetruck 1? of the car and provided with contact members 20f resilientconducting material rigidly attached to the contact board 1 andinsulated therefrom by means of slabs of insulating material 2 and 2".Alongthe track, on the cross ties thereof, are contact members 3 mountedby means of spring hinges 3 in brackets 3 so as to yield in eitherdirection longitudinally of the track when engaged by the contactmembers Each contact member?) preferably consists of a middle rib 3 ofmetal to give it strength, and a contact plate 3 on one side thereof,preferably of brass, and an insulating block E on the other side thereofand preferably extending up past also in electrical connection with therail 1,

and it willlbe seen that any electrical conductingsys'tem on the vehiclethat is connected to one of the contact members 2 thereon and connectedto conducting parts of the-vehicle will form part of the completeelectrical circuit. lVith these details provided it is only necessary toarrange the contact members 2 in a series across the vehicle along thecontact board 1, as best shown in Fig. 3 of the drawings, and arrangethe contact members 3 on the track in corresponding positionstransversely of the track, so that different contact members Qwill makecontact with the different contact members 3 and thus provide selectiveconnections which may beutilized in forming different circuits throughthe different contact members 2 on the vehicle.

The contact members 2 on one side of the contactboard 1 are for makingelectrical connection when the vehicle is traveling in one direction,and those on the other side areto make such connection when thevehic1eis=traveling in the opposite direction, and anapron 2 is securedto the contact board 1 along its middle and hangs down between thecontact members 2 on the two sides. It is to co'ciperatewith thisarrangement that the track contact members 3 are so constructed as tomake electrical conducting contact on one side and insulating contact onthe other side as engaged by the contact members on the vehicle, and itwill be seen that the insulating apron 2 not only prevents contactbetween adjacent contact members 2 on the two sides of the contact board1 but prevents contact of members 2 on one side with track contactmembers 3 that should make contact only with members 2 on the otherside. Furthermore, each station the approach of the vehicle to which isto be signaled is provided with twoof the track contact members 3, eachhaving its electrical connecting side away from the station and beingspaced the distance away from the station that it is required to havethe signal of the approach to such station disclosed. Then when thevehicle approaches the station the forwardly presented contact member 2on the contact board 1 will make electrical connection with the trackcontact member 3, but when leaving a station the contact member 2 willengage with the insulating side of said contact member 3 and noelectrical connection will be made. This arrangement may be clearlyunderstood upon inspection of Fig. 15 of the drawings where thediiferent stations are designated as Sta. 1, etc, and the track contactmembers corresponding to the various stations are indicated as S. 1,etc, the direction of travel of the vehicle in which the respectivecontact members will make electrical contact with the contact members onthe vehicle being indicated by small arrows accompanying thedesignations of the track contact members on the diagram. It will benoted that the track represented in this diagram as supplied withcontact members according to my systemis endless. However, it will beunderstood that with the track contact members arranged as shown thevehicle may be turned around on the track and the order of contact ofthe contact members on the vehicle with those on the track will bemaintained. Thus, the car may run on to the V at A in Fig. 15 or may beturned as on a loop at the end of a line and the order of operation ofthe station signals will not be changed.

"W hen a large number of stations are to be indicated it becomesnecessary to provide for different connections in number equal to thenumber of different stations to be indicated, and this number may bemore than the space available between the rails of a track will permitwhile securing the proper spacing between the contact members as theymust be mounted on the vehicle to make the selective engagements. Asillustrated, the number of connections required is provided by using aplurality of contact boards 1.

In Fig. 3 the contact board 1 is illustrated as provided with thirteencontact members 2 on a single side of a contact board. This would allowthe indication of thirteen stations while the vehicle is traveling inone direction and the equal number which would be provided on the otherside of the board would allow the indication of the same thirteenstation's while the vehicle is traveling in the other direction.

However, in the diagram in Fig. 1 as well as in the track diagram inFig. 15 a single contact board is provided with only four contactmembers 2 on each side, this being for the purpose of simplifying theillustration.

The apparatus for indicating the stations comprises an annunciator 5having shutters 5 with springs 5 to open them and held shut by hooks 5which may be released from the shutters under the action ofelectro-magnets 5 Sixteen of such shutters are provided as indicated inFig. 1, and to correspond therewith four contact boards 1 are providedeach having four contact members 2 on each side making a total ofsixteen contact members. Each contact board 1 is hung on a lever 1 andthe levers are fulcrumed on hangers 1" inside a suitable case 1 that ismounted on the truck 1 by means of a beam 1 having a. brace 1 The lever1 extending past the hanger P has a weight 1 on the other end heavyenough to act as a counterweight to the contact board 1 with its contactmembers 2 and hold said contact board up 'so that the con tact members 2cannot engage with the contact members 3 as the vehicle runs along thetrack. To bring the contact board into position so that the contactmembers 2 may engage with the members 3 an electro-magnet 1 is mountedin the case 1 so that it may attract the weight 1 upward allowing theopposite end of the lever 1 to godown with the contact board 1. Thecontact board 1 is guided at each end by sleeves l sliding on verticalrods 1 which are-attached to the case 1. As shown, two of the contactboards 1 have their levers extending toward one side of the vehicle andthe other two extend toward the other side so that the arrangement ofthe parts is better facilitated.

The conductors 2 from the contact members 2 to the correspondingelectro-magnets 5 in the indicating apparatus are carried through aflexible conduit 1 from the truck 1 up to the car body 1 The indicatingapparatus or annunciator 5 is mounted on the wall 1 of the car body in aposition convenient for observation, preferably over the entrance to thecar, and the conductors "2" are carried a up to-- it through :aJconduit1". Ea ch conductor 2is simply connected to one end of the coil of itscorresponding of current simply being indicated by the.

positive sign in the diagram. It will be understood that the source ofcurrent may be primary or secondarycells carried on .the vehicle, orwhere electric lighting is pro vided on the vehicle, part of the currentof this system may be shunted into the lead 6, or, if the vehicle beprovided with electric motive power, part of the currentithus providedmay be used in the same manner.

I11 all cases the source of current being located on the vehicle,inconveniences incident to providing current along the tracks for anysignal system is avoided, and the current supplying apparatus may alwaysbe kept in perfect condition due to the more constant attentionireceivedfrom the operatives of the railway.

By again referring-to Fig. 15 it will be noted that the sixteen stationsindicated in the diagram are arranged in four groups or divisions offour stations each to correspond to the four contact boards, each havingfour contact members on each side as indicated in Fig. 1. Thus arrangedonly four difierent locations transversely of the track are required forall of the contact members along the track and for those on thevehicle.With this understood itwill be seen that when the thirteen contact"members are permitted to be arranged transversely of the vehicle as inFig. 3, a total of fifty-two stations may be indicated withfourdifierent contactboards 1 and by divid ing the fifty-two stationsinto four groups of thirteen stations each. This division of thestations into groups and'the bringing of the corresponding contactboards linto operative position aseach group isreached is effected byproviding the divisional controlling contact members 7 about mid-waybetweenthe last station of one group and [the first station of the next.Such a'conta'ct member 7 on the trackwill serve "to intro duce the carinto either division as the car travels in one direction Or the other,and in Fig. 15 these members are designatedas D' -D'*, etc., and thedirection in which the car is traveling to be introduced into onedivision or the other is indicated by small arrows adjacent to thedesignations. To engage with this contact member 7 on the track a.controlling contact member 8 is mounted on each contact board 1.Preferably. the divisional contact member 7 is mounted outside the railof the track and the member S'maybe mountednear the end of the contactboard '1 where it extends out under the :action of the magnet 1Toprowide .for' this engagement when the car is turned around on thetrack anothermember "8 is provided near the other end of the con- .tactboard 1 at the other side of the vehicle,

over the raih "Dike-the other contactfinenr .bers 2 on thisboardthecontact member 8 may not engage with its corresponding member 7.. unlessthe board 1 is lowered only part ofthismember being shown in Fig. 3.Unlike the members 2 and members 3 electrical contact may take placebetween the members 8 and the members 7 when the vehicleapproaches ineither direction and in accordance with this requirement I prefer toconstruct the contact member 7 'in the form of a segment, its uppersurface sloping from its middle to its ends, and to construct thecontact member 8 on the vehicle so that it is similar to the contactmembers 3 on the-track in that it is hinged in the bracket 8 andcomprises a middle supporting rib 8 However, it must make electricalconnection on both sides and the two sides must .be eifectuallyinsulated from each other, and the contactplates 8 are mounted on theinsulating base 8 which covers the sides of the middle rib 8 and extendsdown around itslo-wer end8 as best illustrated in Fig. 4. The plates 8have transverse ribs 8 formed on them at their lower ends to makescraping contact with the track contact member 7 asthey slide over it,and the entire lower end of the member 8 is given a convex or recedingformation so that the member 8 may not bind onthe member- 7 should thevehicle start backward and pre-. sentthe member. 8 endwise to the member7. The member 7 may consist in a segmental wooden block 7 of the shapeabove-described with its upper surface faced with a metal plate 7"preferably of brass, the entire member being held down bylag screws 7"driven into the cross ties 4* ofthetrack.

One end ofthe coil on each electro-magnet 1 is grounded through aconductor 9 and an electro-magnetically controlled switch 10 isprovidedfor each magnet 1, to one pole/10' ofwhich the other end of the coil ofthe respective'magnet 1 is con- 115 nected by means of a conductor 1 Theother pole 10 of each'switch is connected to the lead 6, so that if thetwo poles 10' and 10 of the switch 10 are connectedby a bar 10 a currentwill flow from the lead 120 6 through the coil of the respective magnetl energizing it so that it lowers the contact board 1 for which itisprovided. To throw the bar 10 into engagement toconnect the two poles 10and 10 of the switch 10an 125 electro-magnet 10 is provided on eachswitch, and the member 10" that supports the bar 10 is provided with aniron pad 10? (Fig. 13) to be attracted vby the magnet l0 when it isenergized. Another magnet 10.

is opposed to the magnet 10" and acts on a pad 107 on the support 10 ofthe switch bar 10 to withdraw the switch bar 10 from 'mounted on acarrier 10 and provided with a lug 10 engaging with said carrier so thatit will not yield to the support 10 of the switch bar 10 to allow it torecede from the magnet 10, but so that it will yield in the otherdirection to allow the switch bar support to recede from the magnet l0under the action of the magnet 10. Thus the switch is positively heldopen and requires that the stop-pin 10 be withdrawn from engagingposition to allow the switch to be closed. To thus withdraw the stop pin10 its carrier 10 has an iron pad 10 which may be attracted by anelectro-magnet 10 when said magnet is energized.

3T0 effect the application of the various contact boards 1 in the orderof travel of the car or vehicle along the track in either direction,.theswitch 10 that controls the operation of the magnet 1 on each contactboard has its electro-magnets 10", and 10 connected to the contactmembers 8 on the next adjacent contact board 1 in each instance, theterminal contact boards being considered as adjacent in this connection.The coil 10 of each switch is connected to the contact members 8 on thecontact board which it controls. In the diagram in Fig. 1 the contactboards as represented are designated as are the different divisions inthe diagram of the track in Fig. 15, as D D D and D while the indicatorson the indicating apparatus are designated by the numerals of thestations A to A.

The two contact members 8 provided on each contact board with their twosides insulated from each other are represented in the diagram by twodistinct rectangles for each contact member at the corresponding ends ofthe contact boards. Thus, as represented, the forward side of thecontact member 8 at one end of the board is connected to the rearwardside of the contact member 8 at the other end of the board. As indicatedin Fig. 3, the contact members on the track are to be considered as onthe left hand side of the track looking toward the vehicle as itadvances with the contact board D forward. Thus understood, theconnections between the contact members 8 on the contact boards and thecoils of the electro-magnets of the switches 10 on the control board maybe traced. Taking the contact board D for example a conductor 8 leadsfrom the forward side of the contact member 8 on the left and from therearward side of the contact member 8 on the right to the control boardand is connected to-one end of the coil of the electro magnet 10 of theswitch that controls the current supplied to the magnet 1 of the controlboard D The other end of the coil of the magnet 10 is connected to oneend of the coil of the magnet 10, and the other end of the coil ofthemagnet 10 is connected to the lead 6 that supplies current. Theconductor 8 is also connected to one end of a coil 10 of the-magnet 10in the switch that controls the current to the magnet 1 of the controlboard D and this conductor 8 also is connected to the corresponding coil10 in the switch of the control board D Now if the contact board D belowered so that the forward side of the contact member 8 on the leftengages with a track contact member 7 current will flow through thecoils of the electro-magnets 10 and 10 thereby closing the switch 10 andallowing current to flow and energize the electro-magnet 1 that bringsthe control board D? down. As the same time the current flowing aroundthe coil 10 of the magnet 10 in the switch of the control board D onwhich the contact has taken place will cause this switch to open andinterrupt the current to the elec tro-magnet 1-of saidcontact board Dwhereupon the weight 1 will raise the con-. 7

tact board D out of operative position. The rear side oi the member 8 atthe other end of the board D also connected to the conductor 8 will notcome into use except when the vehicle is turnedaroun'd on the track, asmust be. provided for.

It will thus be seen that by the change of connectionsas the vehiclepasses from the third division to the fourth as at B in Fig. 15, thecontact board for this 'division'is brought 1 into operative position.should the vehicle be traveling in the opposite direction and come intothe fourth division from the first division, in continuing around thetrack as at C in Fig. 15, the rear side of the contact member18 at theleft end of the contact board D would operate by engaging with the trackcontact member 7 at the end of the fourth division, and for this reasonsaid rear side of the contact member on the contact board D is connectedto the conductor 8 along with the forward side of the correspondingmember 8 on the contact board D and the switches l0'will be operated ina similar manner, in this case raising the contact board D in stead ofthe contact board D It will be noted that in both instances the magnets10 on the switch of the board D and the switch of theboard D were bothenergized and in each case where the switch was.

Now

closed it was opened by themagnet and where the switch was already openthe action of the magnet wasmerely to' maintain it open. T Thearrangement of the connections: between the other contact. boards and 1the V other switches is identical with thearrangement above described inconnection with the contact boards D and D and their 5 'and result inclosing the switches in 013-- posed order from that above described, andalso in opening such switches. Also when thus engaging in the oppositedirection the current passes around the other coil 10 of theelectro-magnet 10 in each instance. This provision of separate coils forthe two circuits for the forward and retrograde movement of the vehicleavoids short. circuiting as would occur with a single coil on the magnetat this point.

The shutters 5 on the indicating apparatus or annunciator 5, as will benoted in Fig. 7, are arranged in groups horizontally of the apparatus. Arod 5 extends go along under each group and has pins 5 thatextend up toform stops for the shutters 5 when they come open. These rods5 arenormally ,held back by springs 5 but may be drawn forwardbyelectro-magnets 5 and close any shutter that may be 'openvin the group.The electro-Inagnets 5 of all the groups have current supplied. to themfrom the main 6 through a conductor 5 as will:

be seenin the diagrams in Figs. 1 and 17, 40' and the coils of two ofthem, viz z-ethe one of the first group and the one, of the t'hirdgroup, have their; other endsconnectedqto aco'nductor. 5F while those ofthe secondandv fourth groupsare connected .to a conductor 5. A series ofpoints 5 is provided to each group of shutters, one of said points beingadjacent to each shutter,- and the shutters havingrflexible tongues 5 to,momentarily contact with the points 5 as the shutters-come open. Thisis best illustrated in Fig. 8 of the drawings. All of the points of thesecond and: fourth groups are connected by means of conductors 5 to jthe conductor 5 and all of those'of the ""firstand third groups areconnected by a conductor:5 to the conductor 5. The tongues 5" on theshutters are in electrical connection with the shutters and groundedtherethrough and through the case of the 00' "annunciator, which may beof metal; f In the diagrams in- Fig s. 1' and 17 these groundedconnections. are represented by conductors leading to the conductor 9.Thus arranged,

when any shutter opens in one group itwill 66 act to close any one orall shutters open in fore I do not wish to be understood aslimitadjacent group closing of the last opened 7oshutter-by theopeningof the next shutter will' be effected throughout the series. The insideof. the tongue 5 has an insulating covering 5" that prevents connectionon contact with the point 5 when the door closes. Preferably, the rods 5are positioned some distance from the front of the casing, and eachshutter 5 has a segmental lug 5 for engagement with the correspondingpin 5 on therod 5.

lVith the use of the above-described apparatus the installation of asignal system for indicating stations or transmitting otherpredetermined signals on a railroad is simplified by the avoidance ofany material change in the track or rolling stock, and the applicationof the system to an indefinite number of stations is made possible bythe provision of the successive groups of opera tive elements and themechanism for effecting the changes from one group to the next as thevehicle runs in either direction on the road.

\Vhile I have herein shown and described specifically certain precisedetails of construction it will be understood that various modificationsmay he made in the minor details of my invention without departure fromthe scope and spirit thereof, and thereing myself to the precisespecifications and illustrations contained herein, but
